      Description

      Long Tube Header Performance. The Flowtech HDR 63-74 Chevy/GMC TRK 2/4 WD improves exhaust flow and enhances engine output by replacing restrictive factory manifolds with long tube headers. This design optimizes exhaust scavenging to increase horsepower and torque, ideal for enthusiasts seeking better performance and efficiency in their classic trucks.

      Durable Construction And Finish. Made from .049 inch mild steel tubing, these headers are precision engineered with mandrel bending for smooth exhaust flow. They feature formed collectors with a 3-bolt flange attachment and are coated in high-heat resistant black paint for a durable, satin sheen finish that offers both protection and a stealthy appearance under the hood.

      Installation Ease. Installation is straightforward and includes all necessary mounting hardware and gaskets to ensure a leak-free fit. No drilling is required, making it accessible for both seasoned mechanics and skilled hobbyists.

      Application. This header fits 1963 through 1974 Chevy and GMC 1/2, 3/4, and 1-Ton pickup trucks equipped with 230, 250, or 292 inline 6-cylinder engines in both 2WD and 4WD configurations. It is designed for racing use only and is not CARB compliant, limiting street use.
